FINGER TOOTH-'BRUSH.

SPECIFICATION forming part of Letters Patent No. 628,185, dated July 4, 1899.

Application filed December 22, 1898. Serial No- 699,983. (No model) 1'0 a'ZZ whom it may concern:

Beit known that I, CHARLES W. RICHARDS,

a citizen of the United States, residingin the city and count-y of San Francisco, State of Oalifornia,.have invented an Improvement in Finger Tooth-Brushes; and I hereby declare the following to be a full, clear, and exact description of th'e same.

My invention relates to a brush for cleansing the teeth and in a novel construction and mounting of the same.

It consists, essentially, of a tip adapted to fit the finger and having bristles or other like cleansing devices affixed to the exterior end, so that when applied to the finger it may be used for'cleansing the teeth.

Referring to the accompanying drawings, Figure 1 is asection through the brush. Fig. 2 shows the application of bristles. Fig. 3 is a detail of a bristle made of celluloid or rubber.

The object of my invention is to providea convenient device for cleansing the teeth which occupies a small compass when not in use and Which may be employed without the disagreeable effects of striking the teeth with the hard handles usually employed for toothbrushes.

The body or support consists of a tube A of sufficient length and size to be fitted upon a finger of the hand. The tube may be made of rubber, gutta-percha, aluminium, celluloid,

or anyother'suitable or convenient material.

As here shown, it is closed at'the outer end, so as to form a sort of cot, which -fits snugly and closely upon th e finger, and the closed end is formed with perforations A to permit the air within'the tube to escape when the tube is placed upon the finger, thereby preventing the formation of an air-cushion within the tube. Upon one. side this tube has the surface extended, so as to make an approximately level surface, as shown at a, and upon this surface, which is thickened, as

shown, are fitted the bristles or other like rubbing or cleansingparts B. These bristles, which may be considered to represent any cleansing projections or surfaces, may either be made of the usual materials-inserted and secured in the surface a or if made of rubber they consist of a number ofsmalp'rojecting points \vhitilnserile.; lle jng ,QHERQQ as the ristles: These cleansing-points are preferablylonger at the outer end, as shown at b, forming a concave surface to the inner end 19 which has slightly less projection than the outer end. These points when made of be are'preferably cylindrical, and the ends are foTTfid, assliow'IT'at b in the enlarged view, so as to provide converging points, which points will penetrate crevices and indentations between and upon the teeth and thoroughly cleanse the surface.

By applying this device to the finger, which is flexible and easily turned about, all the and points projecting from said thickened side and having their outer ends converging to a point.

In witness whereof I have hereunto set my hand.

CHARLES W. RICHARDS.
